Cross Browser Testing

Cross browser testing is the process of testing the web application frontend on many different browsers and versions thereof. Web browsers run their home-grown engines to generate user interfaces based on HTML, CSS, and JS source code.

EngineBrowser
GeckoFirefox (and derivatives like SeaMonkey & Waterfox)
BlinkChromium (and derivatives like Chrome, Edge, Vivaldi, Brave & Opera)
WebKitSafari (and all iOS browsers)

All in all, given the different combinations of browsers (& versions), operating systems (& versions), screen sizes, and resolutions, the number of combinations is staggeringly high; and supporting the most popular permutations is vital for businesses.

Why is cross browser testing required?

  • Running on different operating systems and different architectures can introduce rendering and performance differences across browsers.
  • All browser engines are developed independently and support different web specifications to different extents. Some browsers might provide experimental features ahead of others.
  • Not all browsers support all features at the same time. The site ‘Can I use’ lists the level of support provided by different browsers for any given feature.
